AM642 EVM has one PCIe slot and AM642 SK has one USB slot.
AM64 SoC has one SERDES module which can be used by either PCIe or USB.
Add DT nodes to represent and enable SERDES/PCIe/USB modules in EVM/SK.

AM64 has one PCIe instance which can be configured in either
host mode (RC) or device mode (EP). Add PCIe DT node for host
mode and device mode here.
